You were right, the link-speed jumps to 1.3 when 3DMark is running. I finally plugged the eGPU to the VGA port of my screen and switch video source when I want to play, but I'm still curious, is it possible to use eGPU power through intel HD4600 ? Thanks for your help, your community has been a huge source of inspirations.

Hello, I have built a fanless and small desktop PC i5 4570s (HD4600 iGPU) PCI Express Gen 3 I have set up a EGPU with PE4L-HP060A and a Nvidia GTX650Ti. When I'm not playing I use the iGPU (no noise) and I want to turn on the eGPU only when I'll be playing games. So far the GTX650Ti is working, when I plug my screen on the DVI port of the eGPU I can run games in high settings (I get P4600 at 3Dmark11) but I have two questions : - GPU-Z tells me the GTX650Ti is on PCI express Gen 3.0 @ x1 1.1 : How can I set it to 1.2 or 1.3 ? - I first intalled the 331.82 version of nvidia drivers, then I followed that tutorial to mod the driver for Optimus and reinstalled it (I checked the make new install) Obviously it didn't work, I can't get the nvidia control panel to open when the screen is pluggeg on the intel HD DVI port, and when I plug the screen on the eGPU I dont see the Preferred graphics processor option in the NVIDIA control panel. Is there something I am missing to activate the Optimus driver for my eGPU ? Is it possible to play game accelerated by the eGPU with the screen plugged on the intel HD DVI port ? (just like internal LCD on a laptop) Thank you in advance. JayZu
